Bortezomib Impurity 43 CAS 513-36-0 chemical structure

Description

Bortezomib Impurity 43 (CAS 513-36-0) is a certified pharmaceutical impurity reference standard with the molecular formula C4H9Cl and a molecular weight of 92.57 g/mol.

Based on its molecular formula C4H9Cl, Bortezomib Impurity 43 contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 92.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Bortezomib Impurity 43 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
